The Stylus is a utensil that is used to operate the lower screen on the Nintendo DS (commonly called the touch screen). The Nintendo DSi XL has two different sized styluses, one full sized, and the other slightly bigger than the Nintendo DSi's stylus. Animal Crossing: Wild World has two different control schemes: one that is entirely controlled by the buttons on the DS, and one that is controlled entirely by the stylus. Input from the method not currently in use will cause Wild World to switch control modes; however the initial input will not be recognized until used again.
